🗑
|
||||
| acidic solution | show 🗑

||||
| polar molecule | show 🗑
|
||||
| show | Process of association of a substance with the partial positive and/or negative charges of water molecules.
🗑
|
||||
| show | Not readily with water; having less affinity for water molecules than they have for each other.
🗑
|
||||
| show | The attraction that the molecules at the surface of a liquid may have for one another.
🗑
|
||||
| salt | show 🗑
|

|
||||
| covalent bond | show 🗑
|
||||
| ion | show 🗑
